分时资金博弈副图指标公式--看穿主力
一、通达信公式解析
这是一个监控机构与散户资金流向的指标。它通过计算单笔成交额（公式中的20万是个分界线）来区分大额和小额交易，并分别统计它们在上涨和下跌时的累计值，从而估算出“机构”和“散户”各自的买卖力度。
核心输出是“机构买”（红色线）和“机构卖”（绿色线），能直观对比大资金的进出方向。此外，公式还定义了“强势”（机构买入占比>50%）和“拉升”（机构净买入力度大）等状态，并用黄色或红色柱状线在图上进行提示。帮助判断走势主要由哪类资金驱动。
二、公式如下CTA1:=V*C/100,NODRAW;
CTA2:=SUM((IF(((CTA1/8>20) AND (CLOSE>(REF(CLOSE,1)))),CTA1,0)),0);
CTA3:=SUM((IF(((CTA1/8>20) AND (CLOSE<(REF(CLOSE,1)))),CTA1,0)),0);
CTA4:=SUM((IF(((CTA1/8<20) AND (CLOSE>(REF(CLOSE,1)))),CTA1,0)),0);
CTA5:=SUM((IF(((CTA1/8<20) AND (CLOSE<(REF(CLOSE,1)))),CTA1,0)),0);
CTA6:=((CTA2+CTA3)+CTA4)+CTA5;
